Does water cure a cold? No. That’s time’s job. Time and your immune system.
But does water help? Yes. A thousand times yes. It makes the misery slightly less miserable. It keeps your engine running while the repair crew (your white blood cells) works overtime.
So drink up. Nurse that glass of water like it’s the last drink in a desert. Your nose will thank you. Your throat will thank you. And your future self—the one who feels human again in three days—will definitely thank you.
Now go refill your glass. I’ll wait.
